とができる。With the above structure, when carrying the copying machine body 1,
When 17 is pulled out, the base 17b rotates and the receiving portion 2 of the rising plate 26
6c is pressed. Then, the rising plate 26 rotates about the shaft 26a, and the push-up portion 26b rotates in the arrow H direction. Then, the sheet cassette 6 is brought into contact with the bottom plate 6a of the sheet cassette 6, the sheet cassette 6 is pushed up, and the sheet 4 is pressed against the sheet feed roller 10. Therefore, it is possible to prevent the disorder of the paper 4 being carried.
そして、複写機本体１を再設置して、把手17を元の位置

紙カセツト６も下がり給紙状態の位置に復帰する。Then, when the copying machine main body 1 is reinstalled and the handle 17 is returned to the original position, as the rising plate 26 is lowered downward, the paper feeding cassette 6 is also lowered and returned to the position of the paper feeding state.
このように、上記実施例と同様の効果を有している。In this way, it has the same effect as the above-mentioned embodiment.
なお、本考案は、上記実施例に限定されるものではな
く、本考案の範囲内で上記実施例に多くの修正および変
更を加え得ることは勿論である。It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.
例えば、第二実施例において、押え板23に反時計方向に
付勢するばねを取付け、押え板23を用紙４から離間させ
るようにしてもよい。For example, in the second embodiment, a spring that urges the holding plate 23 in the counterclockwise direction may be attached to separate the holding plate 23 from the sheet 4.

可能となるといつた優れた効果がある。<Effects of the Invention> As is apparent from the above description, according to the present invention, the paper feed roller presses the paper in the paper feed cassette in association with the pull-out operation of the handle when carrying the main body of the copier. It is possible to prevent the paper from being disturbed due to vibration and shock when carrying the main body, and to prevent a paper feed error due to the paper to be disturbed when the main body is reinstalled. Further, since the existing paper feed roller is used as a member for holding the paper in the paper feed cassette when carrying the copying machine body, it is not necessary to provide a special member, and the structure can be simplified and downsized. In that case, it has an excellent effect.
